​The purpose of the book is to propose and exploit an analytical, critical, well defined theory of a very crucial human social relation that I call “Tutelarity/ Tutelage”. This will thus explain how/why such relation is so relevant at any layer of sociality: from affective relationships, to social cooperation and interactions, to politics and democracy. The approach is theoretical and strongly grounded on cognitive science and the models of human mind: beliefs, desires, expectations, emotions, etc. Written in an accessible way, it will be of interest for a large audience, specifically to researchers and scientists interested in cognitive science and the dynamics of social relationships alike.
